On the Move is a short book, as it is the text of a speech Bono gave at the National Prayer Breakfast in 2006, illustrated with photos he took (and that were taken of him) on his visits to Africa.
Say what you will about him, he has used his position as the front man for U2 to help millions of people. He co-founded DATA (Debt, AIDS, Trade, Africa), EDUN (a fashion brand committed to source production from Africa), the ONE Campaign (which fights poverty), and Product Red (which engages businesses in the fight against AIDS).
The main point of his speech was to encourage richer nations such as the US to commit just 1% of their budgets to help those in the poorest countries of the world. He uses the commonalities of major religions - Judaism, Christianity, and Islam, all of which command followers to help the poor - to appeal to the consciences of those in power.
Like Bono, I was disillusioned at an early age by organized religion. You need only turn on the TV on Sundays to see megachurches which spend millions on their buildings, sound systems, and TV coverage instead of doing what Jesus would be doing were he here today. "Religion often gets in the way of God."
But religions at their best can do a tremendous amount of good in the world, a point Bono made in front of people of all religious and political beliefs in 2006.
